摘要： The valve is designed to be connected to a sanitary waste pipe system for admitting atomospheric air into the waste pipe towards the valve function elements in response to a pressure reduction in the system in order to protect the water traps in the system and to prevent discharge of contaminated air from the system to the atmosphere. It includes an oblong bowl-shaped valve housing (10), a vertical tubular member (12) extending downwards from the housing (10) and adapted to be connected to the waste pipe system, an inner space (18) within the valve housing (10) and containing the valve function elements (34), at least one passage (26) from the valve function elements (22) towards the surrounding atmosphere and a cover member (14) overlying the inner space and having a top wall spaced above the valve function elements (20, 22, 34). The valve housing (10) is provided with at least two valve function elements (20, 22, 34) each having a circular valve seat (20) extending downwards in order to create a tubular space (22) within and connected to the valve housing (10), and a movable valve member (34) having a bowl shaped central portion (36) and a peripheral conical edge (38) extending upwardly, the outer surface of which is resting on the circular valve seat (20) in closed condition.
